  • This paper presents an evaluation of feasibility studies conducted to justify investments in infrastructure projects. An analysis of a previous feasibility study for a highway construction project is presented in this paper with an emphasis on the estimates and forecasts presented in that study in order to weigh expected benefits from the project against expected costs. The forecasted numbers are compared with actual data collected during the operation phase about the usage of the facility. The comparison reveals a huge difference between estimated numbers and actual numbers. Based on the lessons learned from the analyzed case study, recommendations are presented to improve feasibility studies for infrastructure projects including: peer review of feasibility studies; before-and-after feasibility studies; and defined scope and methodology for feasibility studies. Decision makers are advised to take outcomes of feasibility studies for infrastructure projects with extreme caution as some studies may provide erroneous and misleading input to their decisions regarding investment in infrastructure projects.

  • This paper proposes an approach in Southeast Asian studies using a post-colonial framework in the study of post-colonial Southeast Asia. This framework is based on the sociology of knowledge that analyzes the dialectical relationship between science, ideology, and discourse. Post-colonial studies is critical of the concept of universality in science and posits that a scientific statement of a society cannot stand alone, but is made by authors themselves who produce, use, and claim the so-called scientific statement. Several concepts in post-colonial theories can be used to develop area studies, i.e. colonial discourse, subaltern, mimicry, and hybridity. Therefore, this study also explores these concepts to develop a more comprehensive understanding of Southeast Asian culture. The development of post-colonial theories can be used to respond to the hegemony of social theories from Europe and the United States. The main contribution of area studies in the field of the social sciences and humanities is in revealing the hidden interests behind the universal social sciences.

  • Despite considerable commitment to the application of action learning as an organization development intervention, no identified systematic investigation of action learning practices has been reported. Based on a systematic literature review, the purpose of this paper is to identify whether researchers strike a balance between action and learning in their studies of action learning. Research findings in this study included: (1) only 32 empirical studies were found from the electronic database search; (2) based on the hypothesized continuum of Revans' original proposition of balancing action and learning, the author categorized 32 studies into three groups: action-oriented, learning-oriented, and balanced action learning; (3) there were only nine studies on balanced action learning among 32 empirical studies, whose insights included an effective use of project teams, applications of action learning for organization development, and key success factors such as time, reflection, and management support; (4) case study was among the most frequently used research method and only six quality studies met key methodological traits; and (5) therefore, more rigorous empirical research employing quantitative methods as well as case studies is needed to determine whether researchers strike a balance between action and learning in studies on action learning.

  • Objectives The goal of this review is to investigate clinical and experimental studies on external application treatment for atopic dermatitis in Korean literature and to propose for the better method of clinical studies in order to seek more effective treatment. Methods Electronic researches were performed with KTKP, OASIS, National Assembly Library, Korean Medicine Database, KISS, DBpia, and KISTI. Results and Conclusions In Twenty six studies, the numbers of clinical and experimental studies are respectively 10 (38.46%) and 16 (61.54%). The numbers of studies that used herbal complex were 20 (76.92%), and out of that, 6 studies had used a single herbal medicine (23.08%). The external application with oriental medicine for the atopic dermatitis used with Phellodendri Cortex (7), Sophorae Radix (6), Scutellariae Radix (6), Lonicerae Flos (5), Coptidis Rhizoma (5) and so on. Among the clinical studies, the 5 studies were double-blind and randomized-controlled study (50%). The numbers of studies that used Hanifin and Rajka Diagnostic Criteria (1980) were 6 (60%), and that used the Diagnostic Criteria in Korean Atopic Dermatitis (2005) were 4 (40%). Among the clinical studies, categories to evaluate of atopic dermatitis are respectively SCORAD Index (80%), Total IgE (80%), Eosinophil count (70%) and so on. All of the clinical studies (100%) showed a statistically significant decline in atopic dermatitis according to the SCORAD Index, Modified SCORAD Index, the Clinic index score. Among the experimental studies, the numbers of studies that used NC/Nga mice were 9 (56.25%), and out of that 5 studies used BALB/c mice (31.25%). Most of the studies (68.75%) used DNCB as allergy inducing materials. The scales for evaluation of atopic dermatitis were Clinical skin severity score, Histopathologic examination, Immunohematologic examination, safety test and so on. In 12 cases (75%) of experimental studies, the IgE level of experimental group showed a statistically significant decline after using external application. In 8 study cases (50%), Clinical skin severity score of experimental group showed a statistically significant decline after using external application.

  • The main purpose of this study is to examine the concepts appeared on researches and provide the future research directions in field of child health nursing. A descriptive study was conducted. 205 studies were included in an analysis the concepts in terms of the domain of client for a total 321 researches. All were originally published between 1990 and 2000 in Korea. An analysis of concepts for this study was used the metaparadigm framework for nursing proposed by H.S. Kim(2000). The concepts for this study were categorized by essentialistic concepts, problematic concepts, health-care experiential concepts with the following results. 1. Based on the four domains suggested Kim (2000), 205 studies(63.9%) belong to the domain of client ; 109 studies(34%) belong to the practice domain of nursing; 3 studies(0.9%) belong to the client-nurse domain; and 4 studies belong to the domain of environment, respectively. 2. In the domain of client, 117(57.1%) studies used concept of parent. Among them, mother was the prevailing research population(103 studies). 64 studies(31.2%) used child population and the developmental stage of children varied from preterm to puberty but school aged children was the most target population(28 studies). Family as a concept of client was used in 20 studies(9.8%) but most primary care provider was the mother. 3. In terms of research design, non-experimental design(83.5%) is the most and among them survey was 159 studies(77.6%). Qualitative research(23 studies) and experimental research(10 studies) methods were used relatively few. 4. In terms of the categories of concepts, 196 (61.4%) studies included the essentialistic concepts like stress and coping(20.4%), mothering role and child care(7.8%), health (5.6%), breast feeding(4.7%). 31 studies included problematic concepts like power-lessness, safety, obesity, pain, anxiety. And 65 studies included health-care experiential concepts like compliance, growth, hope, environment but relatively few. The findings of this study provide the evidence that research related problematic concept and health-care experiential concept should be conducted actively to improve the practice of child health nursing. Also to deeply understand the phenomena of client in field of child health nursing, interpretive research methods should be conducted actively, too.

  • 본 연구는 해방 이후 현재까지 우리나라 중학교 사회과교육과정의 변천 과정을 정리하고, 그에 따른 지리교육의 목표와 내용 변화를 통합구조와 수준에 초점을 맞춰 분석하는데 목적이 있다. 연구 결과를 정리하면 다음과 같다. 첫째, 교수요목기부터 제3차 교육과정까지 중학교 사회과교육의 지리, 역사, 일반사회는 분과적으로 운영되었으나 제4차 교육과정에서 제7차 교육과정까지 중학교 사회과교육과정의 실질적 통합 요구가 강해졌다. 2007 개정 교육과정 이후 역사가 사회과교육과정으로부터 과목 독립하고, 학년마다 배치되었던 학제적 통합 단원도 사라지는 등 통합교과로서 사회과교육의 정체성이 흔들렸다. 그럼에도 불구하고 지리와 일반 사회만으로 구성된 중학교 사회과의 기형적 통합구조는 여전히 유지되고 있다. 둘째, 사회과 통합에 대한 요구가 강할수록 각 학문영역 간 시수 확보 경쟁 또한 치열해져 학습자의 학습 부담도 증가했다. 그리고 중학교 사회과 통합구조는 지리학과 지리교육의 간극을 점차 벌렸고, 지식과 학생 경험의 괴리도 넓혔다. 이처럼 중학교 사회과 통합구조는 지리교육과정의 목표와 내용 조직의 상위 요인으로 작용하여 의미 있는 지리교육과정을 개발하는데 걸림돌로 작용했다.

  • The purpose of this study is to analyze the trend of nursing research related to family support and to provide an effective direction for future research by conducting a review of the Korean nursing literature from 1980 to 2000. A total of 73 studies were analyzed with the following results. 1) The number of studies related to family support has been rapidly increasing since 1984, and 77% of those were conducted in the 1990s. 48 studies, 65% of those analyzed. were degree-based research including 4 doctoral theses (4%) and 45 master's theses (62%). 2) Based on the objective frame of study types developed by Lee et al. (991), the types of studies were analyzed: 56 studies, 76.6% of those reviewed, belonged to factor-relating: 9 studies (12.4%) belonged to factor-isolating: 7 studies (9.6%) belonged to situation-producing: and only 1 study (1.4%) belonged to situation-relating research, respectively. 3) In terms of research design, most studies of analyzed (90.4%) were conducted by non-experimental design, and 7 studies (9.6%) were conducted by experimental design. But, qualitative research related to family support was not found. 4) In terms of research subjects, target populations of experimental studies were patients with arthritis, mental disorder, tuberculosis, coronary artery disease and hypertension. In correlational studies, 51 studies, 69.9% of those analyzed, were conducted to patients with renal failure, cancer and hemiplegia, and 5 studies (6.8%) were conducted to aged people and adolescents. 5) Study concepts used in correlational studies were quality of life, anxiety and depression, self-esteem, hope, role behavior, compliance and self-care activities. The quality of life was most often used among studies with 12.5% of those analyzed. 6) Nursing interventions, including diet therapy, family involving education and supportive care, used in experimental studies mostly showed positive effects on client involvement and home health improvement. However, the nursing interventions of mental health rehabilitation and resistance exercise showed neutral and negative results. The findings of this study provide evidence that more empirical research including experimental or qualitative studies should be conducted actively to improve nursing practice related to family support. Also, to promote more diverse nursing interventions, a family assessment tool especially for Korean families needs to be developed.

  • 본 연구는 동유럽의 지역에서 한국학 전문가의 양성의 필요성과 그 가능성에 대해 논의한 것이다. 한국학 전문가의 필요성에 대해서는 지역 전문가로서의 한국학 전문가의 역할을 세 가지로 정리하여 그 근거를 제시하였다. 그것은 1)자국에서 한국을 올바로 알리고 대변하는 역할, 2)해당지역에서 한국학을 유지하고 발전시키는 데 있어서의 중심적인 역할, 3)한국문화를 제대로 알리고 보급 및 확산시키는 중심적인 역할을 들 수 있겠다. 아울러 동유럽 지역에서의 한국학 전문가 양성 가능성에 대해서는 루마니아의 바베쉬-보여이대학, 헝가리의 엘테대학, 불가리아의 소피아대학에서 운영하는 한국학 전공 강좌의 실태를 통해 구체적으로 살펴보았다. 현재 이들 대학에서 운영하고 있는 한국학 전공의 강좌 현황, 재학생 및 교수진의 상황, 한국학에 대한 국내외의 관심과 지원 등을 구체적으로 비교 검토하였다. 아울러 논의를 통해 드러난 문제점을 짚어 보고, 그에 대한 현실적인 개선책을 알아보았다. 마지막으로 해외 대학의 한국학 전공 유지 및 발전은 각 지역 출신의 한국학 전문가 양성을 위해서는 반드시 필요한 일이므로 한국정부기관의 지속적인 관심과 지원뿐만 아니라 현지에 진출해 있는 한국 기업들의 적극적인 관심과 지원도 필요하다는 것을 제안하였다.
